CHARLES KING, OFGRAND RAPIDS, MICHIGAN.

CARPET-SWEEPER.

$PECIFICATION forming part of Letters Patent No. 636,002, dated October 31, 1899.

Application filed June 13, 1898. Serial No. 683,360. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES KING, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

My invention relates to improvements in the manner of supporting and manipulating the pans in an automatic pan-action carpetsweeper; and its object is to so support an automatic pan in a carpet-sweeper that the inner edges may be actuated vertically and the outer edges dumped without danger of warping the pan. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective of a sweeper-case in section on the line y y of Fig. 2; and Fig. 2 is an elevation of the supporting and actuating mechanism, showing the yoke cut off on the line a; 00 of Fig. 1.

Similar letters refer to similar parts throughout both views.

In the accompanying drawings, A represents the case, and 13 represents the handlebow.

The pans F in this sweeper are not attached to the case at any point. The front edges are pivoted upon the pins 0 at the lower ends or extremities of the yoke O, which is suspended in the case upon the connecting-bars b, which extend out through the slot a in the end of the case and connect the yoke with the lower ends of the handle-bow, so that when the motion of the sweeper is reversed,

as in the alternate motions in sweeping, the yoke is carried from side to side, asindicated by its dotted lines, which in connection with the supporting of the outer edges of the pans on the bearings a causes the inner edges of the pans to reciprocate vertically, so that the pan toward which the sweeper is moving will be thrown to the surface being swept, while the opposite pan will be raised from said surface. I wish it to be particularly noted that these yokes are made of a single piece of metal without a joint or flexible bearing; also, that they are not pivoted or otherwise connected to the ends of the case at any point, but are arranged to impart motion directly from the handle-bow to the pans, said motion being at right angles with the motion of the handle-bow. The outer edges of the pans are supported and actuated by means of the angle-levers D, the ends of the pans being pivoted near the outer edges upon the pins cl at the end of the longer arm of said levers, so that the throwing of this end down, as indicated by the dotted lines to the left of Fig. 2, willcarry the outer edges of the pans down and dump them, the pivot-point of the pans for this action being the pin a at the ends of the yokes.

My appliance for preventing the pans from warping consists of the equalizing-rods D, that are integral with and rigidly connect the shorter or upper arms of the lever D, so that one lever cannot be actuated independent of the other, by which means it is rendered impossible to warp the pans.

The pans may be held to normal position by any suitable spring, as E, applied in a proper manner to have the desired effect. I prefer the form shown in Fig. 1, where the coil of the spring is secured to the ends of the case, and the free ends are made to act upon the equalizing-bar D to actuate the angle-levers D, as indicated.

The levers D have supporting-arms d,which pass into or through the ends of the case to act as pivots for the levers to turn upon, and one of them passes through the end of the case and is connected to the dump-lever Gfor dumping the pans.

My reason for using a solid yoke connected only with the handle-bow and the pans is twofold: First, if the yoke is divided at the point of connecting with the handle-bow, as in my Patent No. 555,655, it requires staples or other devices near the ends to hold them in place, so that the inner edges of the pans will always assume their normal position when under the direct influence of the actuating springs, while with the solid sliding yoke it is not necessary to use any extra precautions in this direction. V I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In combination with a sweeper-case and pans therein, a handle-bow journaled in slots in the ends of the case, yokes pivoted near their center to the handle-bow and at their ends to the inner edges of the pans whereby the levers to hold the pans to normal posithe inner edges of the pans maybe raised and tion, substantially as and for the purpose set lowered by the movement of the handle-bow forth.

in said slots, angle-levers pivoted to the case, Signed at Grand Rapids, Michigan, June 5 one arm of each of said levers extending out 8, 1898.

and pivotally connected with the outer edges of the pans, and one arm extending up above the pan; with a bar rigidly connecting the In presence ofvertical arms of each pair of levers, and D. C. MORLEY, ro springs attached to the case and acting upon I. J. CILLEY.
